Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Please see Figure 1This utility model provides a technical solution: a millimeter-wave laser level gauge, including a system host, a liquid volume monitoring terminal, and a material tank 110. The system host mainly consists of an explosion-proof cabinet 120 and an industrial touch screen 121. The industrial touch screen 121 is fixedly installed inside the explosion-proof cabinet 120. A sliding door is hinged to one side of the explosion-proof cabinet 120. The liquid volume monitoring terminal includes a radar level gauge 130 and a bracket assembly 140. The bracket assembly 140 is fixedly installed on the top of the material tank 110. The radar level gauge 130 is installed on the bracket assembly 140. The detection end of the radar level gauge 130 passes through the top of the material tank 110 and extends into the interior. The radar level gauge 130 is electrically connected to the industrial touch screen 121.
[0023] In some specific implementation schemes, an audible and visual alarm 122 is fixedly installed on the top of the explosion-proof cabinet 120. The audible and visual alarm 122 is electrically connected to an industrial touch screen 121. The industrial touch screen 121 displays the compartment number, liquid level, volume data, and high / low alarm status in real time. When the liquid level is abnormal, the audible and visual alarm 122 emits sound and flashes a warning, realizing an immediate warning of abnormal liquid level. When the liquid level reaches the preset high / low alarm threshold, the audible and visual alarm 122 can quickly emit sound and flash a warning, effectively reminding the operator to pay attention, thereby enhancing production safety and reducing potential risks caused by abnormal liquid level.
[0024] In some specific implementations, the liquid level data signal measured by the radar level gauge 130 is transmitted to the industrial touch screen 121 via RS. The RS transmission protocol is used to achieve stable and efficient data transmission between the radar level gauge 130 and the industrial touch screen 121. This ensures the real-time performance and accuracy of the liquid level data, provides operators with reliable liquid level information, facilitates timely monitoring and adjustment, and improves production efficiency.
[0025] Please see Figure 2 and Figure 3The support assembly 140 includes a first support frame 141, a second support frame 142, and a support plate 143. Side plates 144 are symmetrically fixedly installed on both sides of the first support frame 141. The side plates 144 are fixed to the top of the material tank 110 by first bolts. Guide rods 145 and threaded rods 146 are respectively fixedly installed at the top of the two side plates 144. The second support frame 142 is threaded onto the threaded rods 146 and slidably mounted onto the guide rods 145. Support rods 147 are fixedly installed at the four corners of the bottom of the second support frame 142. The support plate 143 is fixedly installed at the bottom of the support rods 147. A radar level gauge 13 is also included. The 0 is installed on the support plate 143. The top of the tank 110 and the top of the support plate 143 are provided with round holes that match the output end of the radar level gauge 130. The guide rod 145 and the threaded rod 146 are symmetrically arranged. The bottom of the support plate 143 is provided with a positioning groove that matches the first support frame 141. The first support frame 141 is slidably connected to the inner wall of the positioning groove. The first support frame 141 is fitted on the outside of the round hole. The bottom of the support plate 143 is fixedly installed with a sealing plate. The top of the guide rod 145 and the threaded rod 146 are fixedly installed with a turntable. The diameter of the turntable is larger than the diameter of the guide rod 145 and the diameter of the threaded rod 146.
[0026] In some specific implementations, a positioning ring 148 is fixedly installed on the top of the support plate 143. The positioning ring 148 is fixedly connected to the outside of the radar level gauge 130 by a second bolt. The outside of the positioning ring 148 is provided with multiple threaded holes that match the second bolt, and the outside of the radar level gauge 130 is provided with threaded grooves that match the second bolt, ensuring the stability and firmness of the radar level gauge 130 during installation and use. This design effectively prevents the radar level gauge 130 from falling off or loosening, thereby ensuring the continuity and accuracy of level measurement.
[0027] Working principle: In use, the radar level gauge 130 is installed on the support plate 143 and fixed by the second bolt and the positioning ring 148. The first support frame 141 is placed on the top of the material tank 110 and fixed to the material tank 110 by the first bolt and the side plate 144. At this time, the turntable on the threaded rod 146 is rotated. The rotation of the threaded rod 146 drives the second support frame 142 to move. The movement of the second support frame 142 drives the support plate 143 to move through the support rod 147 and fit against the top of the material tank 110. At the same time, the movement of the support plate 143 drives the radar level gauge 130 to move until the detection end extends into the material tank 110. At this time, the radar level gauge 130 can perform real-time monitoring and transmit the data to the industrial touch screen 121 for display.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
